She tweeted "There's no place like home" Thursday morning, less than 24 hours after leaving the hospital and seeing the sun and sky for the first time in 30 days.

"After 30 days in the hospital I'm home," her tweet continued. "Praise God from whom all blessings flow. Thank YOU and bless YOU. XO"

GMA showed video Thursday morning of Roberts' first encounter with fresh air since she underwent the transplant in her fight against a rare blood disease called myelodysplastic syndrome, or MDS.

Roberts' sister, Sally-Ann, was her donor. The two were pictured in the GMA video in Roberts' New York apartment admiring the view.

Her GMA colleagues have been prolific in their on-air mentions of Roberts since her absence, as well as of #teamrobin, the Twitter hashtag that's caught fire since she announced her latest health battle in June.
